Extender by General Finishes is a liquid that you may add to any water-based stain, topcoat, milk paint or glaze. This wetting additive is used to improve flow and leveling. It extends the dry time, giving you more time to work with the product. This is especially helpful when working in hot, dry climates. Extender is a must-have product on hand when using Glaze Effects or using a dry brush technique. DO NOT USE EXTENDER WITH OIL-BASED PRODUCTS, SUCH AS GEL STAINS.
Pour into GF water-based products as needed in small increments. Start with 5% and then increase up to 15% by volume. Stir well before use.
